Answer:
Point-slope form: y + 3= -1(x + 4)
Slope-intercept form: y = -1x - 7
y = m * x + b,
where:
m is the slope; and
b is the intercept of the y-axis.
To find out the time in between a different time you can add in segments, you can add 15min to 2:45, to make it 3:00, then add 60 more minutes to make it 4:00, so now we have 75 min, then add 20 minutes to get the time to 4:20 pm, you then add up all the segments, which equal 95 minutes. In hours it would be 1 hour, and 35 minutes. Hope you understand that, of not, tell me, and ill fix it and make it more understandable.
Answer: 4^3
(Four cubed or Four to the power of 3)
Step-by-step explanation:
Finding the parabolas roots.
-x^2+4x=0
-x(x-4)=0
x=0 and x=4

![[-x^3/3+2x^2]](https://tex.z-dn.net/?f=%5B-x%5E3%2F3%2B2x%5E2%5D)
(top is 4 and bottom is 0)
-64/3+32=32/3
The area above the x axis is 32/3
